Replying to [comment:9 Lars Aksel Opsahl]:
> With no snapping (zero Tolerance in the Topology)
Just a note: right now there is NO WAY to request no snapping (see #5688),
so what where you referring to here ? Is it 0 precision in the topology
record ? In that case a snapping tolerance is computed based on the input
line distance from origin.
I agree on a max_edges parameter, will work on a pull request for that.
